gantt chart maker for scheduling algorithms

Gantt chartĪ Gantt chart is a bar chart that shows processes formed against time. But, before we dive into the details, let’s look at what a Gannt chart is.

There is a high average waiting time that causes a starvation problem.Ī ready queue and Gantt chart should be used to perform this algorithm.

Due to the non-preemptive nature of the algorithm, short processes at the end of the queue have to wait for long processes that are present at the front of the queue to finish.

Its implementation is easy and it is first-come, first-served.

It is the simplest form of a scheduling algorithm.

The lesser the arrival time of processes in the ready queue, the sooner the process gets the CPU. This means that the process that requests the CPU for its execution first will get the CPU allocated first. First Come First Serve (FCFS)Īs the name suggests, the First Come First Serve (FCFS) algorithm assigns the CPU to the process that arrives first in the ready queue. This article will focus on two different types of non-preemptive CPU scheduling algorithms:įirst Come First Serve (FCFS) and Shortest Job First (SJF). Non-preemptive scheduling is employed when a process terminates or transitions from running to waiting state. Preemptive scheduling is when a process transitions from a running state to a ready state or from a waiting state to a ready state. There are two main types of CPU scheduling, preemptive and non-preemptive.

This switching ensures that CPU utilization is maximized so that the computer is more productive. It forms the basis of multiprogrammed systems. CPU scheduling refers to the switching between processes that are being executed.
